Edmond Halley figures in the early history of the Royal Society,  an English astronomer, geophysicist, mathematician, meteorologist, and physicist, known for the comet named after him, whose periodicity he accurately calculated. In 1676, Halley visited the south Atlantic island of Saint Helena and set up an observatory with a large sextant with telescopic sights to catalog star catalog of the southern hemisphere and visit astronomers in France and Italy. While there he observed a transit of Mercury across the Sun and realized that a similar transit of Venus could be used to determine the absolute size of the Solar System.  In 1679, Halley published the results from his observations on St. Helena as   Catalogus Stellarum Australium  which included details of 341 southern stars.  In September 1682 he carried out a series of observations of what became known as Halley’s Comet, though his name became associated with it because of his work on its orbit and predicting its return

Orion is visible in both the Northern and Southern hemispheres.

Instantly recognizable Northern and Southern hemispheres. The three stars of Orion's belt are easily located, even in the city. The brightest star in the constellation is called Rigel and is 40.000 times brighter than our sun. If you draw an imaginary line through Orion's Belt it will lead you to the brightest star in the night sky called Sirius. Just above the belt stands pumpkin-colored Betelgeuse (say BET‘l-juice) and just below it shines blue-white Rigel (RYE-jill). Both are super-large. Then let the belt point down and leftward to the brightest star in all the heavens. This is the Dog Star Sirius. In the Northern hemisphere, the constellation can be seen from late autumn to early spring. In the Southern hemisphere, Orion can be seen in the summer months, note that it will appear upside down. December, January, February are the warmest months in the Southern Hemisphere. The constellation is located on the celestial equator, halfway between the north and south celesti
